Vavu yofukula solenoid TM66001 24V 20Bar hydraulic pump proportional solenoid valve

Mfundo yogwirira ntchito ya excavator solenoid valve
 

Wofukula makamaka amagwiritsa ntchito valavu ya solenoid yolunjika, yomwe ili ndi ubwino wowongolera bwino, kuchitapo kanthu mofulumira, kosavuta kukwaniritsa kulamulira kwakutali, ndipo imatha kugwira ntchito nthawi zonse pansi pa vacuum, kupanikizika koipa ndi zero. The excavator solenoid valve ali ndi chipinda chotsekedwa mkati, thupi la valve liri pakati pa chipindacho, ndipo malekezero awiri a thupi la valve amapangidwa ndi ma electromagnets malinga ndi zosowa, kapena mapeto amodzi okha amapangidwa ndi ma electromagnets. Pogwiritsa ntchito mphamvu ya maginito yopangidwa ndi mfundo ya inductance, spool yolamulira imasuntha kuti ikwaniritse kusintha kwa dera la mafuta, pamene coil ya electromagnet ikapatsidwa mphamvu, maginito amakokera mbali ina, ndikukankhira spool kuti asunthire mbali ya kuyamwa, potero kutsekereza kapena kuvumbula mabowo osiyanasiyana amafuta, ndipo mafutawo adzalowa mapaipi osiyanasiyana molingana ndi malangizo. Ngati coil ya solenoid ya solenoid valve itenthedwa kapena kudulidwa, sichitha kupanga mphamvu ya maginito, ndipo chigawo cha valve sichingasunthidwe, ndipo wofukula sangagwire ntchito zina.

Vavu ya solenoid pa pampu ya hydraulic nthawi zambiri imakhala ndi ziwiri, imodzi ndi valavu ya TVC solenoid, ina ndi LS-EPC solenoid valavu, yoyambayo imakhala ndi udindo wozindikira chizindikiro kuchokera ku sensa ya injini, kusintha mphamvu ya injini ndi pampu ya hydraulic. machesi mphamvu, ngati kuonongeka, mwina injini ndi yodzaza ndi galimoto, osakwanira mphamvu, kapena injini ndi kovuta kuyamba.
Wotsirizirayo ali ndi udindo wowona ntchito ya dalaivala ndi kusintha kwa kukula kwa katundu wakunja, ngati kuonongeka, kumayambitsa kufooka pakukumba, kugwira ntchito pang'onopang'ono kwa makina onse, luso losauka laling'ono, komanso palibe zida zothamanga kwambiri. Tiyenera kukumbukira kuti pali valavu imodzi ya TVC solenoid isanayambe ndi pambuyo pa mpope, ndi valavu imodzi yokha ya LS-EPC.
Ma hydraulic pump drive shaft sangathe kupirira mphamvu ya radial ndi axial mphamvu, kotero sikuloledwa kukhazikitsa mawilo a lamba, magiya, ma sprockets mwachindunji kumapeto kwa shaft, nthawi zambiri ndi cholumikizira kulumikiza shaft yoyendetsa ndi shaft pampu.
Ngati chifukwa cha zifukwa zopangira, mlingo wa coaxial wa mpope ndi kugwirizana umaposa muyezo, ndipo pali kupatuka pa msonkhano, mphamvu ya centrifugal imawonjezera kusinthika kwa kugwirizana ndi kuwonjezeka kwa liwiro la mpope, ndipo mphamvu ya centrifugal ikuwonjezeka. Zotsatira za kuzungulira koyipa, zotsatira za kugwedezeka ndi phokoso, motero zimakhudza moyo wautumiki wa mpope. Kuphatikiza apo, palinso zinthu zina zomwe zimalimbikitsa monga kumasula pini yolumikizira osati kumangitsa panthawi yake, kuvala mphete za rabara komanso osati kusinthidwa munthawi yake.
